TURNING ON ELECTRICAL POWER TO UNIT
Turn on electrical power to Unit. Operational status of Unit is now being displayed as fault messages on control
panel message display. The following fault messages will be continuously displayed at 2-second intervals until
necessary operation requirements are satisfied.
‘‘OFF 1’’ (Beater Motor No. 1 not operating)
‘‘OFF 2’’ (Beater Motor No. 2 not operating)
‘‘H
2
O OUT’’ (No water supply to Unit)
‘‘CO
2
OUT’’ (No CO
2
gas supply to Unit)
‘‘SYRUP 1’’ (No syrup supply to Unit No. 1 syrup system)
‘‘SYRUP 2’’ (No syrup supply to Unit No. 2 syrup system)
TURNING ON CO
2
SUPPLY TO UNIT
1. Open CO
2
cylinder valve slightly to allow lines to slowly fill with gas, then open valve fully to back seat
valve. Back-seating valve prevents leakage around valve shaft.
IMPORTANT: If bag-n-box syrup supply system will be connected to Unit instead of soft drink tanks,
primary CO
2
regulator (see Figure 2) must be adjusted no higher than 80-psi maximum.
2. Adjust primary CO
2
regulator (see Figure 2) by turning regulator adjusting screw to the right (clockwise)
until regulator pressure reads 80 to 100-psig. OUT OF CO
2
warning light on control panel message display
should have gone out.
3. Pull up on product blender tanks relief valves to purge air from tanks.
4. Remove Unit lower access panel as instructed for access to carbonator secondary CO
2
regulators (see
Figures 2 and 6).
5. Check product blender tanks secondary CO
2
regulators with 60-psi gages for pressure setting which
should be set at 30-psi for best textured product. If further adjustment is necessary, adjust as instructed.
IMPORTANT: Carbonator secondary CO
2
regulator must be adjusted 25-psi higher or more above
product blender tanks secondary CO
2
regulators pressure settings. Carbonated water and syrup
pressures must be able to overcome and vent product blender tanks head pressures while tanks are
filling with carbonated water and syrup. Carbonator tank secondary CO
2
regulator not adjusted high
enough will cause decreased flow of carbonated water into blender tanks which will increase brix of
dispensed product.
6. Adjust carbonator secondary CO
2
regulator, with 100-psi gage, by turning regulator adjusting screw to the
right (clockwise) until gage reads 60-psi.
7. Pull up on carbonator tank relief valve plastic cover to purge air from tank.
TURNING ON PLAIN WATER SUPPLY TO UNIT
Open plain water inlet supply line shutoff valve. Check for water leaks and tighten or repair if evident. ‘‘H
2
O
OUT’’ fault message should have gone out but ‘‘BM 1 OFF’’, ‘‘BM 2 OFF’’, ‘‘SYRUP 1’’, and ‘‘SYRUP 2’’ fault
messages will continue to be displayed.
CONNECTING SOFT DRINK TANKS TO UNIT SYRUP SYSTEMS
IMPORTANT: Product shutoff valves, located in lines leading from product blender tanks to freeze
cylinders (see Figure 2 and 6), must be closed at this time. Closing valves prevents product from filling
freeze cylinders while checking BRIX of product in product blender tanks.
1. Close product shutoff valves, located in lines leading from product blender tanks to freeze cylinders, to
prevent product from entering cylinders.
